You know what USB is, right? It's the small, flat plug that you might have on the computer end of the cables for your mouse, keyboard, printer, joystick etc.
As far as I can work out, what you have is a thing to plug multiple USB plugs into a single socket so you don't have to keep plugging and unplugging. I don't think it's very useful unless you have a ridiculous amount of different accessories. |
